A 4-hi leveler bends the strip through four work rolls; a 6-hi adds a third roll above and below, so the strip passes more alternating bends before it leaves the machine. That extra pair of bends is what the five differences below come down to.

  1. Higher leveling precision
    The 6-Hi Leveler machine adopts more sensors and data feedback mechanisms during the leveling process, make it more accurate than the 4-Hi Leveler machine. At the same time, during the design and manufacturing process, the 6-Hi leveler machine pays more attention to detailed design and control of every link, so that it maintains high precision throughout the entire leveling process.
  2. Better Safety Performance
    The 6-Hi Leveler is better than the 4-Hi Leveler in terms of safety performance. During the entire leveling process, each control parameter has undergone strict safety audits. At the same time, the leveling machine has also adopted more safety measures when designing, such as emergency shutdown, automatic monitoring and other functions to ensure the safety of the operator’s safety.
  3. Better Operating Performance
    Compared with the 4-Hi leveler, the 6-Hi leveler has better operating performance. The six-layer leveling machine can achieve more automated control, reduce manual intervention to a minimum, and make the operation relatively easier. The operator can complete the entire leveling process through simple operation settings, and the operator’s work intensity is relatively small.
  4. Longer Operation Life
    Since the 6-Hi leveler uses more precision technology and materials during the entire manufacturing process, and pays more attention to details during the manufacturing process, the 6-Hi leveler has a longer life than the 4-Hi leveler.
  5. Lower Production Cost
    Although in some aspects the design and manufacture of a 6-Hi leveler is more expensive than a 4-Hi leveler, it is more accurate throughout the entire production and life cycle. It lasts longer and is less expensive to maintain and upgrade, resulting in a lower overall cost in the long run.
